IMPROVEMENT IN POWERS FOR COTTON-GINS.

Specification forming part of Letters Patent No. 170,782, dated December 7, 1875; application filed October 9, 1875.

To all whom it may concern Be it known that I, LEWIS B. STITH, of Bennetts x Roads, in the county of Sampson and State of North Carolina, have invented certain new and useful Improvements in Power for Cotton Gins; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the uccompan yin g drawings, and to the letters of reference marked thereon, which form a part of this specification.

The nature of my invention consists in the construction and arrangement of a horsepower for cotton-gins, as will be hereinafter more fully set forth.

In the annexed drawing, Figure 1 is a plan view of my invention. Fig.2isalongitudinal vertical secti n of the same through the line :0 0c of Fig. 1. Figs. 3, 4, and 5 are detached views of parts thereof.

A represents a suitable frame-work, in which is a vertical shaft or roller, B, placed upon pivots a a, and provided with a sweep, O, for the attachment of the team. On the shaft or roller B is secured alarge horizontal wheelor drum, D, around which is placed an endless belt, E, passing around a pulley, G, on a horizontal shaft, 1), and on this shaft is another pulley, H, to be connected by a belt with the cotton-gin or other machinery to be driven by the horsepower. Between the wheel or drum D and the pulley G are arranged devices. as hereinafter described, for giving the belt E the proper twist and to hold it sufficiently taut.

These devices consist, first, of a roller, (1, set at an angle, as shown in Fig. 5, and having its bearing in a frame, I, which is movable in suitable guides e e, and can be adjusted out and in as required for tightening the belt,

By this construction of the horse-power I dispense with all costly and complicated machinery, and, if desired, the connection may be made direct by the belt E with the driving-shaft of the gin or other machinery to be driven.

Having thus fully described my invention, what I claim as new, and desire to secure by Lette s Patent, is-

l. The 'ertically-sliding frame L and roller h, in combination with the guides KP, pulley G, wheel D, and belt E, constructed and arranged substantially as described, whereby the roller and frame hold the belt in proper position by their own weight, substantially as and for the purpose set forth.

2. The combination of the angling-roller d, adjustable frame I, vertical rollers f j, and horizontal roller h in the vertically-sliding frame L, all interposed between the drum D and pulley G, to operate upon the endless belt 0, for the purposes herein set forth.

In testimony that I claim the foregoing as my own I aflix my signature in presence of two Witnesses.
